Multiple layers of innate immune response antagonism of SARS-CoV-2

This study generates twelve SARS-CoV-2 viruses with mutations in individual proteins and shows that many have interferon-antagonizing activity and immunosuppressive effects in human cells and mice, with NSP1 and NSP15 having the greatest impact.

Human vascular organoids with a mosaic AKT1 mutation recapitulate Proteus syndrome

This paper creates a vascular organoid model with an AKT1 mutation to study Proteus syndrome and finds AKT inhibitors reverse vascular malformations.

BRD4 directs mitotic cell division by inhibiting DNA damage

This study shows BRD4 is essential for normal cell growth by regulating cell cycle genes and preventing DNA damage during replication and mitosis.

Cell arrangement impacts metabolic activity and antibiotic tolerance in Pseudomonas aeruginosa biofilms

Transgenic Mouse Models Establish a Protective Role of Type 1 IFN Response in SARS-CoV-2 infection-related Immunopathology

This study uses transgenic mouse models to show that a heightened type 1 IFN response protects against SARS-CoV-2-induced immunopathology, with Irgm1 as a potential therapeutic target.

Focused ultrasound-mediated brain genome editing

This paper demonstrates a method to edit the brain genome in mammals using focused ultrasound to temporarily open the blood-brain barrier for CRISPR/Cas9 delivery via intravenous injection.

Ancestral SARS-CoV-2 driven antibody repertoire diversity in an unvaccinated individual correlates with expanded neutralization breadth

The paper examines antibody diversity in an unvaccinated SARS-CoV-2 infected individual, finding that post-vaccination neutralization breadth against Omicron variants is comparable to vaccinated individuals and breakthrough infections.

Impact of abiotic conditions on Fungal Diversity and Comparative analysis of Soil quality of two distinct locations

This study examines the impact of abiotic conditions on fungal diversity and soil quality in two distinct regions of Karnataka, India, highlighting the relationship between soil physicochemical properties and fungal composition.

Mapping morphological malformation to genetic dysfunction in blood vessel organoids with 22q11.2 Deletion Syndrome

This study uses blood vessel organoids from 22q11.2 DS patients to link genetic dysfunction to vascular malformations through single-cell transcriptomics and imaging.

Autoimmunity Risk Gene IRGM is a Master Negative Regulator of Interferon Response by Controlling the Activation of cGAS STING and RIG-I-MAVS Signaling Pathways

This study identifies IRGM as a negative regulator of interferon response by controlling cGAS-STING and RIG-I-MAVS pathways, linking its deficiency to autoimmunity and antiviral resistance.
